general problems of the 2014 Mazda MAZDA3

While accelerating onto a highway, my engine overheating light flashed then stayed on and my acceleration suddenly throttled back and my car started slowing down. I was able to pull over on the shoulder, but there was a close call with a semi bearing down. I had my car towed to a repair shop, where they told me the water jacket had cracked and the overheating caused a blown head gasket. This was repaired and tested. A week later, I got the car up to highway speeds and the engine overheating light flashed again. When I stopped and looked at the engine, there was foamy tan coolant all over the place. Towed it back again and was told the weld had failed. But in trying to find a used cylinder to replace mine, the shop told me that all of their sources said they had no used ones available because the same crack happened on those as well.

Moments after driving my 2014 Mazda 3, I noticed the blue coolant dashboard icon was lit signaling the coolant is cold. As I drove without touching the accelerator, the car abruptly accelerated and I had to slam on the brakes so I would not rear end the car in front of me. Plus, I noticed the coolant dashboard icon turn off also. The cruise was completely off!.

7/27/16 3:30 pm weather clear and dry ¿ temperature 78 degrees mileage about 24,000 all regular maintenance up to date I accelerated onto washington sr 520 eastbound at exit 51 to get up to merging speed. I kept the car in second gear and the engine revved to about 5,000 rpm. I don¿t think I have ever driven the car over 4500 rpm in the nearly 3 years I have owned it. I am not sure why I didn¿t shift into third as I usually do. Third gear is my definitely my preferred gear for this maneuver and it always works well for merging onto a high speed highway. I was greeted with multiple flashing idiot lights for engine, tire pressure and anti-skid. The throttle was unresponsive and I was not able to merge onto the highway safely as my speed dropped rapidly from about 45 to 30. I limped along in the first lane at about 30 mph, I tried to turn on my emergency flashers but I don¿t think they worked. I am not certain of this last point as I was panicked that the engine had appeared to quit just has I was merging into heavy rush hour traffic that was moving at about 60-65 mph. I could not get any power in any gear and tried feathering the throttle. I pulled off the highway at the next exit ¿ about 1 mile. I shut off the engine and let it rest for about 30 seconds. When I turned the car back on, everything appeared normal. No idiot lights and the throttle responded normally. I was able to drive the last couple of miles home without incident. I absolutely love this car but this incident scared the crap out of me.

As I was turning into a parking spot to park my car, the car accelerated on its own and ran into a concrete wall. I have had issues with this car's programming, including when I took my car in to get fixed after the safety recall in January '16. As I realized the car was accelerating - and pushing on the brake would not stop it - I lifted the emergency brake. The crash ultimately stopped the car - not the brake or emergency brake, and the airbag deployed. Less concerned about the damage to the outside of the car, and more concerned that I had zero control over the car and any ability to stop it.

Tl-the contact owns a 2014 Mazda m3s. The contact stated that while driving at approximately 50 mph, the speedometer dropped down to zero and the gas pedal was depressed but the vehicle did not accelerate as all of the warning indicators illuminated on the dash panel. The failure recurred four times. The vehicle was taken to a dealer where it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 6,700. Sg.
